Remedy effects of dandelion and milk thistle on fatty liver hemorrhagic syndrome in laying hens
Fatty liver hemorrhagic syndrome (FLHS) is a metabolic disorder found in caged layer hens and causes reduced egg production and sudden death. Dandelion (Taraxacum coreanum, TC) and milk thistle (Cirsium japonicum var. ussuriense, CJ) are well known wild herbs inhabiting Korean peninsula and presenting antioxidative effects. This study investigated alleviate effects of these herbal mixture (6:4, w/w) composed of dried powder of TC and CJ against fatty liver in laying hens. The herbs mixture 5.0, 10.0, 20.0 or 40.0 g/kg feed was provided via feed admixture for 3 weeks to laying hens having FLHS....

A triplex real-time PCR assay for simultaneous and differential detection of Bordetella bronchiseptica, Mycoplasma cynos, and Mycoplasma canis in respiratory diseased dogs
Bordetella (B.) bronchiseptica, Mycoplasma (M.) cynos, and M. canis are the major bacterial pathogens that cause canine infectious respiratory disease complex (CIRDC). In this study, we developed a triplex real-time polymerase chain reaction (tqPCR) assay for the differential detection of these bacteria in a single reaction. The assay specifically amplified three bacterial genes with a detection limit of below 10 copies/reaction. The assay showed high repeatability and reproducibility, with coefficients of intra- and inter-assay variations of less than 1%. The diagnostic results of the assay u...

Effect of culture-promoting ingredients (CPI-107) on the culture of Mycobacterium tuberculosis
Mycobacterium tuberculosis complex (M. tuberculosis complex) is a causative agent of contagious chronic disease in a wide range of mammalian hosts, mainly cattle, goat, pigs, wildlife, and humans. The definite diagnosis of tuberculosis is made based on culture of M. tuberculosis, but it takes a long time. In the present study, we analyzed whether the detection time of M. tuberculosis could be reduced when cultured in the medium containing the culture-promoting ingredients-107 (CPI-107) using the BacT/Alert 3D system, an automatic culture system. The time to detection (TTD) tended to decrease a...

Virulence factors and antimicrobial resistance patterns of pathogenic Escherichia coli isolated from fecal samples of piglets
Pathogenic Escherichia coli is the cause of a wide range of diseases in pigs, including diarrhea, edema disease, and septicemia. Diarrhea caused E. coli may result in significant economic losses, making pathogenic E. coli an important pathogen for the swine industry. This study investigated the prevalence of virulence factor genes, antimicrobial resistance phenotypes, and resistance genes in E. coli isolated from feces of piglets in Korea between 2017 and 2020. As a result, 119 pathogenic E. coli isolates were obtained from 601 fecal samples. The F4 adhesin gene and the STb enterotoxin gene we...

Analysis of prevalence and risk factors of calf diarrhea using rapid diagnosis kit
Between February 2020 and September 2021, 378 calves with diarrhea were investigated across 96 cattle breeding farms in Korea, using a rapid diagnostic kit. The study examined the infection rates of major pathogens causing diarrhea in calves, which were categorized by season, age, birth month, and region. Additionally, logistic regression analysis was conducted to investigate the factors affecting the infection rate. The study found that the five representative pathogens causing calf diarrhea exhibited differences in infection rates based on season, region, age, and birth month. Bovine rotavir...

The prevalence of viral diseases in wild boars (Sus scrofa) in Gyeongsangnam-do, South Korea
Wild boar is closely related to domestic pigs in terms of genetic homogeneity and the possibility of a source of infection by contact. This study investigated the prevalence of viral diseases from wild boars inhabiting Gyeongsangnam-do, South Korea. A total of 374 blood samples were collected and subjected to antigen tests to detect African swine fever virus (ASFV), Porcine circovirus type-2 (PCV2), Porcine reproductive and respiratory syndrome virus (PRRSV). For seroprevalence, PCV2, PRRS, classical swine fever virus (CSFV), Aujezsky’s disease (ADV), and foot and mouth disease virus (FM...

The medical management of mitral stenosis in a Bull Terrier
An eight-year-old, 28-kg male bull terrier who showed signs of lethargy and cough was referred for further evaluation of congestive heart failure. On presentation, physical examination revealed a systolic murmur at the left apex of the heart. Moreover, chest radiograph evaluation confirmed the mild alveolar and interstitial patterns in the caudal lung lobes and a grossly enlarged left atrium and left ventricle. Electrocardiography showed atrial fibrillation with a wide QRS complex, and transthoracic echocardiography revealed marked enlargement of the left atrium with abnormal morphology of the...

Incidental finding of hemolymph nodes in a Holstein cow (Bos taurus taurus) with coccidiosis
This case report is about hemolymph nodes found in a dairy cow whose function is still not fully elucidated. A 4-month Holstein cow presented severe respiratory symptoms and hematochezia for a while with respiratory acidosis and metabolic alkalosis. Coccidiosis was diagnosed and treated immediately, but the cow died from respiratory acidosis and metabolic alkalosis. At necropsy, no abnormal appearance in thoracic and peritoneal organs was observed, but hemolymph nodes were observed being multifocally stuck on omasum serosa and the subcutaneous fascia of abdominal region, and the larger dark re...

Diagnosis and treatment of the odontoid process fracture of the axis in a dog
A 7-year-old dog weighing 3.9 kg visited the hospital with symptoms of inability to stand and quadriparesis. There were seizure symptoms 2 months before admission to the hospital, and the symptoms of stiffness and rigidity appeared. Radiographs showed normal vertebrae in cervical vertebral column. Magnetic resonance imaging (MRI) and computed tomography (CT) were performed immediately to diagnose vertebral lameness. As a result of the CT, it was possible to observe the fracture of the odontoid process of the axis, and the exact location of the damage was identified. The odontoid process was fr...

Genomic epidemiology and surveillance of zoonotic viruses using targeted next-generation sequencing
Emerging and re-emerging zoonotic viruses become critical public health, economic, societal, and cultural burdens. The Coronavirus disease-19 (COVID-19) pandemic reveals needs for effective preparedness and responsiveness against the emergence of variants and the next virus outbreak. The targeted next-generation sequencing (NGS) significantly contributes to the acquisition of viral genome sequences directly from clinical specimens. Using this advanced NGS technology, the genomic epidemiology and surveillance play a critical role in identifying of infectious source and origin, tracking of trans...
